I use this shen I suspend:

#!/bin/sh
# remove the usbhdi module when suspending
if lsmod | grep '^usbhid' >/dev/null ; then
    /sbin/modprobe -r -s usbhid
fi
if lsmod | grep '^uhci_hcd' >/dev/null ; then
    /sbin/modprobe -r -s uhci_hcd
fi
if lsmod | grep '^ehci_hcd' >/dev/null ; then
    /sbin/modprobe -r -s ehci_hcd
fi
exit 0

and this makes the mouse come back alive when I resume:

bob@t40:~/configs$ cat ins_ext_mouse
#!/bin/sh
# remove the usbhdi module when suspending
if !(lsmod | grep '^ehci_hcd') >/dev/null ; then
    /sbin/modprobe -s ehci_hcd
fi
if !(lsmod | grep '^uhci_hcd') >/dev/null ; then
    /sbin/modprobe -s uhci_hcd
fi
if !(lsmod | grep '^usbhid')   >/dev/null ; then
    /sbin/modprobe -s usbhid
fi
exit 0
